Chapter 9, Problem 9.17E

Interpretation Introduction

Interpretation:

The value of the charge-to-mass ratio, $e/m$, in units of $\text{C}/\text{kg}$ from numbers determined by Millikan is to be stated.

Concept introduction:

Millikan conducted an experiment of oil drop to calculate the charge of electron. He calculated the charge to mass ratio by that experiment for electron. He also proposed that the charge on electron is quantized. The value of charge given by Millikan is $1.601\times {10}^{-19}\text{C}$.
